Compliment her on something she did to her beauty
Another thing gorgeous women are afraid of: nature and time taking its toll. Natural beauty is great, but also fleeting. Make a woman feel that she is in control of her appearance, and you make her feel confident. Tell her you like how her clothes flatter her figure, or how her scarf brings out her eyes, or how her haircut emphasizes her cheek bones. Make her feel that she has the power to make herself look beautiful.
